BACKGROUND Up till now about 400 red cells antigen have been identified. The majority are inherited by Mendelian Fashion. The ABO blood group system was first to be identified and RH blood group system was the 4th one, both are most important for blood transfusion purposes. This study is conducted to determine the frequency of ABO and Rhesus (Rh) blood groups in District Swat, NWFP, Pakistan. I...

Rhesus (Rh) proteins were recently characterized as ammonia gas (NH(3)) channels. Studies indicate, however, that Rh proteins also facilitate CO2 transport in a green alga and in human erythrocytes. Previously, we reported that Rh mRNA expression in various rainbow trout tissues responded to high environmental ammonia. To determine whether or not Rh proteins may also be involved in CO2 transpor...

Immunoperoxidase technique and light microscopy have been used to localize neurosecretory systems for vasopressin, oxytocin and related neurophysins (neurohypophysial peptides)) and gonadotropin-releasing hormone (Gn-RH) in the rhesus monkey brain. All the neurohypophysial peptides were found in the magnocellular nuclei (suproptic and paraventricular) of the hypothalamus and in their projection...

Rhesus (Rh) proteins share a conserved 12-transmembrane topology and specify a family of putative CO(2) channels found in diverse species from microbes to human, but their functional essentiality and physiological importance in metazoans is unknown. To address this key issue and analyze Rh-engaged physiologic processes, we sought to explore model organisms with fewer Rh genes yet are tractable ...

OBJECTIVE To document the distribution of the ABO and rhesus (Rh) blood groups in a random sample of Saudi students from the King Khalid University, Abha, Kingdom of Saudi Arabia, and to compare our results from that of other studies in the Kingdom and elsewhere. METHODS The subjects included in this study were 944 males from the southwest region of Saudi Arabia including Aseer, Jizan, and Na...

The in vivo efficacy of glycosylated and nonglycosylated recombinant human granulocyte macrophage colony-stimulating factor (rh GM-CSF) expressed in Chinese hamster ovary cells and Escherichia coli respectively was studied in rhesus monkeys following a daily subcutaneous (SC; three times) or intravenous (IV; over six hours) dose for seven consecutive days. The monkeys responded to the rh GM-CSF...
